Isn't it a tradition in chinese cuisine to drink and slurp from the bowl?

I just like to pick up on this point. Things that may seem rude in Britain might not be in other countries. Some people find eating food with ones hands rude but I think when it's appropriate it's fine. Finger bowls all the way!

I drink cereal milk from a finished bowl of cereal in my own home. Definitely not in public though.

As for soup, I often pour my soup into a big mug and drink it, and I don't find this unmannerly in any way, I'm using the correct vessel for drinking.

I don't think I've ever drank from the bowl but not through manners through brilliant use of my spoon and bread on the table

There you have it. If you have good bread on the table, as the French do as a matter of course, there is no need to lick the plate or drink from a bowl. Nor need we waste the last traces of sauce, soup or dressing - the bread is there to soak up every last delicious drop and smear

If it can be helped, I personally wouldn't drink from the bowl and use a spoon (soup, cereal, etc). However, I have been to restaurants and ordered the Ramen Soup. It has been given to me in a huge bowl able to mix the ingredients of a cake in. After eating the noodles and left with the soup, you can't help but drink from the bowl because using a spoon would leave you there all night and would eventually become cold and unenjoyable.

All in all, if it can be helped then I wouldn't, but if I want to enjoy my meal then I would.

A friend of mine took out a new, quite posh, girlfriend to an Oriental restaurant and he saw a bowl with a slice of lemon in it - he drank it - then he found out it was the finger bowl !
I don't think he saw her again.
